Pane retainer

PANE RETAINER Filed Feb. '7, 1924 breakage.

In the saine way vthe glass can stand heavy pressures and blows troni.y external objects Without breaking.

rl`he second mentioned form ot the invention, shown in Figs. 3 and 4, is identical with that ljust described in det-ail, with the single exception that the ends of the retainer are pivoted to the side walls of the i'raine near the back wall, instead ot being detachably held in the trame; and are thus anchored to, or interlocked with, the frame in a permanent way. rlhe form of pivot shown in F ig. vLl consists in punching, odsetting inwardly, and rolling the metal of the traine to provide a tubular formation at Z, Fig. a,

similar to a hollow rivet, and by bending the end ot the retainery to `term an eye m which lits the pivot Z and is adapted to turn thereon. Both free ends ot the retainer are treated and held in this manner. Ui course other and equivalent means for pivotally connecting the retainer to the frame ii'iay be used and are within the scope of the protection ot the claim, as tor instance, inserting a separate rivet in the wall ot' the trame and through the eye m, or by` bending out the end of the retainer so as to 'torni in itself a pivot seated in a hole in the frame, or by other means known to those skilled in the art.

lt will be understood that in order to disengage the retainershown in Figs. 3 and t, from the glass, all that is needed is to tree the middle part ot' the retainer from the lugs e, and then swing the retainer as a whole about its pivots away troni the glass. Although the pivoted ends of the retainer still remain in the trame, plenty of room is lett tor inserting and removing the glass, moving it edgewise in an vinclined path. Then in setting the retainer to hold the glass, it is swung about its pivots untilthe middle portion snaps past the lugse. The same springy quality exists between the angles (Z3 of the retainer and the part which is anchored by the lugs e, and also between the angles Z4 and the pivoted ends of the retainer, as already described.

l/Vhat I claim and desire to secure by Letters Patent is: f

l. The combination with a frame having a. pane supporting ledge and side walls, of a retainer consisting of a wire bent to lie abutments adapted to engage the adjacent part oit' the retainer and limit separation thereof trom the plane of the pane, theside portions ot the retainer being odset toward one another and toward the plane ot the pane at the saine time, said offset part having y separated angles arranged to bear against the pane, and being sprung away trom the frame close within two of the opposite side walls Y between said angles, when the middle part I of the retainer is so inter-locked with the adjacent part ot the trame. i

2. lThe combination ot a traine having a pane supporting ledge, a pane bearing against said ledge, and a resilient pane retainer; said retainer being an elongated resilient member formed to be within and generally beside two opposite sides and an intermediate side ot the frame, the extremities ol' the retainer and its middle portion being anchored to 'the traine at points spaced back from the pane, and the side portions of the retainer having offset angles arranged to engage the pane and being so far offsetas to cause the parts ot the retainer between its points ot engagement `and anchorage to be so stressed that said engaging point-s are pressed resiliently against the `pane and to Jard the ledge.

3, The combination with a frame having a pane supporting ledge and side walls, lot a. retainer consisting of ai wire bent to lie close within two of the opposite side walls and an intermediate wall of the trame, the

major partot the retainer being normally ont ot contact with the pane lying against said ledge, abutments on the said walls arranged4 to interlockwith said retainer and prevent accidental withdrawal of the retainer from the pane, the side portions of said retainer being otl'set between their ends toward the said ledge tar enough to exerta constant resilient pressure against the pane at separated points, holding Ythe latter against saidledge.

In testimony whereof I have Vatxed my signature.
